RAIL-ANCHOR.

Specification of Letters Patent.

Patented June 15, 1915- Applieation filed November 26, 1913. Serial No. 803,191.

To all whom it may concern:

Be it known that I, JOHN M. Soon, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in RaiLAnchors, of which the following is a specification.

My invention relates to devices for preventing the longitudinal creep of railway rails, such devices being variously called rail anchors, rail stays or anti-creepers. In order that a device of this sort should suc cessfully perform its intended function it must be strong, compact and so constructed that its grip upon the rail will not readily be loosened by the backward thrust of the rail which is supposed to take place immediately after the train has passed over it, or by other disturbing influences. In order that the device should be salable it must consist of few parts, be easily applied to the rail, be inexpensive to manufacture both with respect to labor and material, and also be light in weight so as to minimize freight charges.

The principal object of this invention is to provide a rail anchor of the wedge type, that is, a device in which the grip on the rail is produced by a wedging action between the relatively movable elements of which the device is composed, Which will have all of the above mentioned qualities and requisites in a maximum degree.

More particularly the purpose of the invention is to provide a rail anchor Which, besides being light, strong, compact and simple in its construction, will consist of elements having a wedging relation with each other, the wedging or frictionally engaging surfaces of contact of which with each other andwith the rail have a considerable aggregate area and are so disposed and designed as to insure a firm and reliable grip between the device and the rail and between the elements of the device when driven into operative position with each The invention has for further obj ects'such other new and improved arrangements, de-

shown in Fig. 1. Fig. 3 is an end elevationof the device. Fig. 4 is a plan view of the movable or wedging element of the device. Figs. 5 and 6 are views of opposite ends of said' element. Fig. 7 is a sectional View taken on line 77 of Fig. 1 Fig. 8 is a plan view of the stationary element of the device, that is, in the preferred form of my invention showrflthe element which is provided with the tie abutting flange. Fig. 9 is a sectional view taken on line 9-9 of Fig. 8, and Fig. 10 is a view, in elevation, of the end of the stationary element with which the movable or wedge element engages.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, A designates a railroad rail formed with the usual base flange B, and C one of the cross ties supporting said rail.-

The rail anchor, in the preferred embodiment of my invention shown, consists of a stationary element or bar D and a movable or compound Wedge element E. The bar D is provided at one end with a hook or jaw 10 and at the other end has a tie abutting flange 11 and is formed with a .slot 12 and beyond the slot with a dovetailed rib 13. The wedge.

element 'E is formed so as to have a jaw 14 which engages the edge of the rail base B opposite to that engaged by the jaw 10 on her D and is provided with a tongue. 15 adapted to extend through the slot 12in the bar D and formed with projections 16, 17"which underlie and bear against portions'of the under surface of the bar D on opposite sides of slot 12. The wedge element is also preferably formed with a rib 18 which with the tongue 15 provides a dovetailed slot 19 into which the dovetailed rib 13 on the bar is adapted to fit.

The device is applied to the rail by hooking the jaw 10 of the bar D over one ed e of the base flange of the rail with the as downwardly upon the same thereby clamping the rail vertically as well as horizontally between bar D and wedge E. The outer edge 20 of the slot 12 is slightly oblique both vertically and with respect to the axis of the rail and the tongue 15 is tapered toward the tie. This causes the jaws 10 and 14 to be drawn together. The under surfaces 21 and 22 of the bar on opposite sides of slot 12 have a slope downwardly toward the tie abutting flange 11 and the surfaces 23,24 of the tongue 15 are given corresponding contours. This results in drawing the wedge element down upon the rail base when it is driven toward the tie. The end of the bar is preferably formed with a rounded wedge surface 25 which is frictionally engaged by a correspondingly formed surface 26 on the inside of the rib 18. The rib 18 is preferably rather thin so that if necessary, in order that the wedge element E should be driven into close engagement with the base flange of the rail, it will reluctantly yield or bend, thus remaining in tight frictional engagement with surface 25. Its function, therefore, is not so much to effect a wedging action between the parts of the rail anchor, this function being performed by the other co-acting wedge surfaces, as to increase the frictional contact between the elements of the device. It will be seen that the aggregate area of the surfaces of the two elements in frictional contact with each other is considerable and when subject to corrosion by exposure to the weather, this engagement tends to become permanent. The surface 23 engages surface 21. The surface 24 engages surface 22. The surface 26 engages the sur face 25,while the flat upper surface of bar D tightly engages the fiat under surface of the rail. wedge surfaces are notin the same plane, which circumstance increases the grip between the elements.

While I have described my invention in a Moreover, these pairs of co-acting' tionary element of the roadbed other than one of the cross ties ordinarily used for sup porting railway rails.

I claim:
